coMBlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 353,224, dated November 231l 1886. Application led March 4, 1886. Serial No. 193,918. (Nomodel.) Patented in Eng'and October 20, 1984, No. 13,839.

T0 all whom it may concern.-

Beit known that we, JOSEPH JEFFERSON, CORNELIUS J EEFERSON, LAZARUS J EEFER- soN, and MOEDECAI JEEEEnSoN, subjects of Her Majesty the Queen of Great Britain, and residents of Bradford, in the county of York,

England, have invented certain new and usestructed, it is found that on starting or restarting the circular combs they move before the dabbing-brushes attain any considerable speed, or before their effective motion is arrived at, so that a portion of the wool or fiber rises, or is not sufficiently dabbed or forced into and among the pins of the combs, and is carried onward without being combed or cleaned and cleared of all noil or waste.

The object of our invention is to obviate the above defect, which we do by the arrangement of parts hereinafter described, whereby the dabbing-brushes are set in motion before the combs, and are enabled to run after the latter have ceased, reference being made to the accompanying drawings, in which- Figure 1 is an elevation of such a portion of the well-known Nobles Combing-Machine7 as is necessary to illustrate our improvement with the combs in section, Fig. 2 being an enlarged sectional View of the driving-pulleys, with a portion of the drivingshaft in elevation. Fig. 3 is an elevation, partly in section, of the combs and mechanism for driving the Same.

Similar letters refer to the corresponding part-s in all the gures.

In the drawings, 1 indicates the main drivingshaft of the machine, on which is loosely mounted a pulley, 4, having an elongated boss, 3, which in turn carries a broad loose pulley, 2, and a narrower fixed pulley, 5. Alongside of the latter, but fixed to the main shaft 1, is

-of which is Xed a gear, 29.

` a driving-pulley, 6. The pulley 5, being at tached to the boss.3, drives it and pulley 4,

which communicates motion by the strap 6,

pulley 7, shaft 8, and cranks 9 to the slides 10 55 10 of the dabbing-brushes 1()a 10, as clearly shown in Fig. 1.

The main driving belt or strap 11 is provided with shifting mechanisms, which may be briefiy described as follows: A suitable 6o shifting-fork is carried upon a bar or rod, S, the arms of said fork extending upon either side of the belt in the usual manner. The rod or bar is supported in bearings b b, so as to have longitudinal sliding movement, and is provided with suitable knobs or handles, e e, at the ends thereof, whereby the bar may be grasped by the hand and given a sliding movement to shift the belt. A lever, a, is also provided to effect this same movement, and, as 7o shown, is provided with a slot, d, through which a pin, d', secured tothe rod o1" bar S, projects.

It will be seen that by shifting the main driving-strap 11 from the loose pulley 2 to the 75 fixed pulley 6, to operate the circular combs 12 12a 12, the strap must first pass to, upon, and in part over the pulley 5, thus communieating motion to the dabbing-brushes before reaching the pulley 6, which, through gear- 8o wheels 13 13 14 14 and vertical shafts 15 15 working in the hollow uprights 16 16, communicates motion to thecircular combs 12 12 12*L and other parts of the machine in the Qrdinary manner.

As shown in Fig. 3, motion is communicated from t-he upright shaft 15 to the comb by a train of gearing. Upon the inner periphery of the comb 12 is a circular rack, 24, into'which meshes the gear 23, journaled upon 9o a suitable pin or stud. The gear 23 receives motion from a pinion, 22, carried upon the upper end of a shaft, 2l, upon thelower end A gear, 18, and pinion 19 are both fixed to a small shaft, as 95 shown. The former receives motion from a gear, 17, on the shaft 15, and the latter communicates motion to the shaft 21 through its gear 20. By this train of gearing the inner circular comb is actuated. The outer comb is also provided with gear-teeth on its inner periphery, and motion to this co'mb is given through teeth 25 on the outer periphery of comb 12L meshing therewith.

The start given to the dabbingbrushes I insures the Wool or fiber being eliectnally dabbed down into the pins before the combs commence to move and rotate'for the purpose of clearing the long fibers of the noil and Waste. The main strap Il drives both pulleys 5 and 6, as shownin Fig. 1.

In stopping the machine, the band Il is transferred clear of the pulley 6, thus ceasing driving the combs, but, so long` as it remains on the pulley', it Will continue giving motion t0 the pulley 4, and consequently the dabbingbrushes, while the speed of the combs is reducing, or even alter they are stationary, until it is transferred to the loose pulley 2.

What We claim as our invention, and desire to secure by Letters Patent, is*

l. In combination `with the dabbing-brushes and combs of a combing-machine, a pulley and intermediate mechanism for driving the brushes, a second pulley, and intermediate mechanism for driving the combs, said pulley being placed at one side of the irstmentioned pulley, a loose pulley situated upon the other side of the iirstmentioned pulley,and a belt adapted in size to act upon both the drivingpulleys at the same time, substantially as described.

2. In combination with the dabbingbrushes and combs of a combing-machine, a main driving shaft and intermediate mechanism for actuating the combs, a iXed pulley on said shaft adapted to receive motion from the driving-power, a loose pulley mounted on a sleeve on the shalt, a pulley tlxed to the sleeve between the loose and iiXed pulleys. intermediate mechanism for communicating the motion of the sleeve to the brushes, and a suitable belt adapted to act upon the fixed pulleys at the same time, substantially as described.
